Damn Yankees by BruceM

Question 5

First name is sufficient. What homewrecker (previously the ugliest woman in Providence, Rhode Island, before her own Faustian bargain) tries and fails to tempt Joe Boyd in Damn Yankees? Gwen Verdon originated the role, and her name is in the name of the song "Whatever [BLANK] Wants."

(As best your smith can tell, this character has no specified last name.)
